Re: Autoconf fooled by AC_FC_LINE_LENGTH

Reading the source comment for AC_FC_LINE_LENGTH indicates that
you should call AC_FC_FREEFORM or AC_FC_FIXEDFORM before you call
AC_FC_LINE_LENGTH. You do not do that. This is not mentioned in
the autoconf manual I'm looking at. I don't know if the source
code comment or the manual is correct (it's been 20 years since I
last used fortran...)

Hi Peter,
thanks for the hint, unfortunately it makes no difference.

Looking at the upstream code I notice
that AC_FC_LINE_LENGTH is the only FC call
while all the rest is F77 based

$ grep _FC

$ grep _F77
AC_F77_FUNC(sgemm$SYMBOLSUFFIX, sgemmsuff)
AC_F77_FUNC(snaupd$SYMBOLSUFFIX, snaupdsuff)
AC_F77_FUNC(sneupd$SYMBOLSUFFIX, sneupdsuff)
AC_F77_FUNC(dnaupd$SYMBOLSUFFIX, dnaupdsuff)
AC_F77_FUNC(dneupd$SYMBOLSUFFIX, dneupdsuff)
AC_F77_FUNC(cheev$SYMBOLSUFFIX, cheevsuff)

and this is fishy.
I need to check it

replacing AC_PROG_F77 with AC_PROG_FC
did the work.
